AN INDEX OF INDEXES. 



The young student may begin) with the conviction that 

 something of value has: been written about everything, if it 

 can only be found. To find it is the difficulty, and to over- 

 come this difficulty so many indexes of different kinds have 

 been made, that now the student needs a catalogue of in- 

 dpxes. It is true that those boys and girls who live in the 

 country, away from large cities where the large libraries 

 are, find it very difficult to get hold of the books they need, 

 even when they know their names. Quite likely some of 

 the Agassiz Chapters might make an arrangement such as 

 they have in Australia, where the great libraries in Mel- 

 bourne and the other large cities have a branch office in each 

 of the little towns for hundreds of miles around, and send 

 boxes, made for the purpose and filled with the books called 

 for, every week or two weeks, to these towns by rail, so that 

 the country people have almost as much good of the big li- 

 braries as those people who live in cities. Of course they 

 contribute to the big library some money, but they have a 

 great many more books to select from than if- the same 

 money was spent on a little home town library.
